I'm not well versed in awk, but you could use cut instead...
command | grep bf1 | cut -d ' ' -f 1
...Or just use Perl
# untested
my @var = map {/^\w+/;$&} grep {/bf1/} `command`;

Hmmm... my guess is the $1. The `` interpolates. You need to escape the
dollar sign with a backslash... otherwise it puts the value of $1 into your
command before executing it.
You might want to use strict, it would have caught that.

Subject: Split on white space from `command` return?
Hi!
I would like to grab the first column (variable width) of data in each
line that will be returned from an external command.
I tried @PSARRAY = `command | grep bf1`; and got just the lines with
data I wanted. The returned data looks like this:
EHCFS001 Booted Down bf1/p20 Windows/MU Yes,Opt,0 12:55:29
VMDFS Booted Up bf1/p14 VM25AS21e16/MU Yes,Opt,0
12:52:12
ORA_1 Booted Up bf1/p18 VM25AS21e16/MU Yes,Opt,0
12:56:25
ps3 Booted Up bf1/p3 custom/MU Yes,Opt,0 12:51:56
ps4 Booted Up bf1/p4 custom/MU Yes,Opt,0 12:51:42
ps5 Booted Up bf1/p5 custom/MU Yes,Opt,0 12:51:22
I need to capture just EHCFS001, VMDFS, ORA_1, PS3, PS4 and PS5 in a
var, array, hash, whatever and I don't care about any of the other data.
A variable would be preferable over array, I think.
I then tried @PSARRAY = `command | grep bf1 | awk -F " " '{print $1}'`
but got the same exact results. Anyone know why it didn't like the awk
command or just decided to ignore it?
If I run command | grep bf1 | awk -F " " '{print $1}' on the command
line I get exactly what I need, why doesn't this work during an external
call?
Running on Linux, Perl 5.6.1
Thanks all.
